关于完全对称Toda系统的不变量

On the invariants of the full symmetric Toda system

Yu. B. Chernyakov, G. I Sharygin, A. S. Sorin

摘要:

本文从\cite{CSS14,CSS17,CSS19}出发,继续研究全对称Toda系统的几何性质。也就是说,我们在这里描述了一个简单的几何结构的交换家庭的向量场的紧群,其中包括户田向量场,即字段,它产生了完整的对称户田系统与Cartan分解的半单李代数。我们的构造利用了半单代数的表示,并且不依赖于Cartan对的可裂性。它是非常接近家庭的不变量和半不变量的户田系统与$SL_n$,介绍了在\cite{CS}。

英文摘要:

In this paper we continue our study of the geometric properties of full symmetric Toda systems from \cite{CSS14,CSS17,CSS19}. Namely we describe here a simple geometric construction of a commutative family of vector fields on compact groups, that include the Toda vector field, i.e. the field, which generates the full symmetric Toda system associated with the Cartan decomposition of a semisimple Lie algebra. Our construction makes use of the representations of the semisimple algebra and does not depend on the splitness of the Cartan pair. It is very close to the family of invariants and semiinvariants of the Toda system associted with $SL_n$, introduced in \cite{CS}.
